Tree Turmeric and Trimipramine

Here is the interaction we found between these two, with the evidence behind it.

Moderate

CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES

Why this applies to Trimipramine

Trimipramine falls under CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES — the group Tree Turmeric interacts with.

Theoretically, tree turmeric might increase the levels and clinical effects of drugs metabolized by CYP2C9.
Preliminary clinical evidence suggests that berberine, a constituent of tree turmeric, can inhibit CYP2C9.
Severity Moderate Likelihood Possible Evidence B

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist for trimipramine: it's an active tricyclic antidepressant (not a prodrug), and part of how your body clears it runs through a liver enzyme called CYP2C9. Berberine, the main active compound in tree turmeric, appears to slow that enzyme down. So in theory, pairing them could let trimipramine build up a bit higher than expected.

What that might feel like is more of trimipramine's usual side effects: drowsiness, dry mouth, constipation, blurry vision, dizziness when standing, or a faster heartbeat. I want to be honest though, this is mostly theoretical and based on early, lower-quality research, so it's not a sure thing. Still, since tricyclics can be sensitive to changes, please run it by your pharmacist or doctor before combining them.

From our pharmacist’s overview on the Trimipramine page

“If you take trimipramine (Surmontil), a tricyclic antidepressant, read this list carefully. Nine of the 139 supplements and herbs on file are rated major, and most touch the heart: several, grapefruit among them, can stretch the QT interval, the heart's electrical reset time, and raise the risk of a dangerous rhythm.”

About Trimipramine

What Is Trimipramine Used For?

Brand names: Surmontil, Trimip, Rhotrimine, Tripramine, Trimp

Trimipramine capsules are used to relieve the symptoms of depression. Both supported products (Trimipramine and Trimipramine Maleate oral capsules) carry this same use.

Depression with an “endogenous” pattern is more likely to improve than other depressive states. In the label’s studies, it worked about as well as amitriptyline in less-depressed outpatients, but somewhat less well in more severely depressed ones. In hospitalized patients, it worked about as well as imipramine.
